Definitions
- This application relates to a thermoplastic resin composition and a molded product made using the same.
- Polycarbonate resins have excellent toughness, impact resistance, thermal stability, self-extinguishing property, dimensional stability, and heat resistance, and accordingly have been used in the manufacture of electro-electronic products such as mobile phone housings, backlight frames, and connectors, among other products.
- Polycarbonate resins have also been used in the manufacture of automobile parts such as head lamps, instrument panels, and lens, and as a substitute for glass in materials requiring transparency and impact resistance.
- Polymethylmethacrylate (PMMA) resin has excellent weather resistance and transparency, and excellent adherence and strength such as flexural strength and flexural strain differing from polycarbonate resin. Accordingly PMMA resin can be used as adhesives, lighting materials, and building materials, among other products. However, PMMA has inferior impact strength compared to that of other thermoplastic resins, so it has limited use in the manufacture of thin products with less than a certain thickness requiring sufficient impact strength.
- U.S. Pat. No. 4,027,073 discloses a surface treatment method using a Si compound and a method of improving the scratch resistance through acrylic UV coating.
- U.S. Pat. No. 5,338,798 discloses a method of using syndiotactic PMMA;
- U.S. Pat. No. 5,292,809 discloses a method of using a fluorine-substituted bisphenol;
- U.S. Pat. No. 4,743,654 discloses single-phase blends of polycarbonate resin and polyalkylmethacrylate.
- thermoplastic resin composition having excellent scratch resistance, impact resistance, and transparency.
- Another aspect of the present invention provides a molded product made using the thermoplastic resin composition.
- thermoplastic resin composition includes: (A) about 20 to about 93 wt % of a polycarbonate resin; (B) about 3 to about 50 wt % of a modified acryl-based copolymer resin; (C) about 1 to about 10 wt % of a polysiloxane copolymer including an aryl group; and (D) about 3 to about 20 wt % of a core-shell graft copolymer.
- the polycarbonate resin (A) can be a linear polycarbonate, a branched polycarbonate, a polyester-carbonate copolymer, or a combination thereof.
- the modified acryl-based copolymer resin (B) may be a copolymer comprising about 20 to about 99 wt % of an aromatic or alicyclic acryl-based monomer and about 1 to about 80 wt % of a monofunctional unsaturated monomer being capable of being copolymerized therewith.
- the aromatic or alicyclic acryl-based monomer may be a (meth)acrylate including an aryl group, or a cyclohexyl group.
- the modified acryl-based copolymer resin (B) may have a refractive index of about 1.50 to about 1.58.
- the polysiloxane copolymer including an aryl (C) may be a polydialkyl-diarylsiloxane.
- the polydialkyl-diarylsiloxane may include about 30 to about 50 wt % of a diaryl group based on the total amount of the polydialkyl-diarylsiloxane, and the polydialkyl-diarylsiloxane may be a polydimethyl-diphenylsiloxane.
- the polysiloxane copolymer including an aryl (C) may be a copolymer of polydialkyl-diarylsiloxane and polydialkylsiloxane.
- the copolymer of polydialkyl-diarylsiloxane and polydialkylsiloxane may include about 50 to about 95 wt % of a polydialkyl-diarylsiloxane and about 5 to about 50 wt % of a polydialkylsiloxane.
- the aryl may include a C6 to C30 aryl such as phenyl, benzyl, tolyl, o-xylyl, m-xylyl, and the like, and combinations thereof.

Abstract
Description
- This application claims priority to and the benefit of Korean Patent Application No. 10-2008-0109848 filed in the Korean Intellectual Property Office on Nov. 6, 2008, the entire disclosure of which is incorporated herein by reference.
- This application relates to a thermoplastic resin composition and a molded product made using the same.
- Polycarbonate resins have excellent toughness, impact resistance, thermal stability, self-extinguishing property, dimensional stability, and heat resistance, and accordingly have been used in the manufacture of electro-electronic products such as mobile phone housings, backlight frames, and connectors, among other products. Polycarbonate resins have also been used in the manufacture of automobile parts such as head lamps, instrument panels, and lens, and as a substitute for glass in materials requiring transparency and impact resistance.
- However, when a polycarbonate resin is used to manufacture a product requiring transparency, the product can exhibit deteriorated scratch resistance characteristics as compared to glass. Polycarbonate resin can also yellow when exposed to sunlight for a long time.
- Polymethylmethacrylate (PMMA) resin has excellent weather resistance and transparency, and excellent adherence and strength such as flexural strength and flexural strain differing from polycarbonate resin. Accordingly PMMA resin can be used as adhesives, lighting materials, and building materials, among other products. However, PMMA has inferior impact strength compared to that of other thermoplastic resins, so it has limited use in the manufacture of thin products with less than a certain thickness requiring sufficient impact strength.
- Accordingly, when a transparent PMMA resin having excellent scratch characteristics is alloyed with a transparent polycarbonate resin having excellent toughness, it is expected that the alloy would exhibit both excellent impact resistance and excellent scratch characteristics.
- However, as mentioned in Japanese application No. 1993-130731, when the polycarbonate resin is alloyed with the PMMA resin, the molecular weights and weight ratio are limited within a certain range due to the miscibility and refractive index difference between the two resins. When the levels are outside of these ranges, there is a concern that a pearl effect, uneven color, and opaque characteristics may be exhibited.
- Accordingly, much research on improving the scratch resistance of polycarbonate has been carried out.
- For example, U.S. Pat. No. 4,027,073 discloses a surface treatment method using a Si compound and a method of improving the scratch resistance through acrylic UV coating. In addition, U.S. Pat. No. 5,338,798 discloses a method of using syndiotactic PMMA; U.S. Pat. No. 5,292,809 discloses a method of using a fluorine-substituted bisphenol; and U.S. Pat. No. 4,743,654 discloses single-phase blends of polycarbonate resin and polyalkylmethacrylate.

However, it can cause problems such as deteriorated haze and transparency even if it is added in a small amount due to the refractive index difference between polydimethyl siloxane and polycarbonate.
- In the present invention, a part of the dialkyl of the polydialkyl siloxane such as polydimethyl siloxane is substituted with diaryl, to improve refractive index and transparency when adding it to the thermoplastic resin composition.
- According to one embodiment, the example of a polysiloxane copolymer including an aryl group includes polydialkyl-diarylsiloxane.
- The polydialkyl-diarylsiloxane may include about 30 to about 50 wt % of a diaryl in the polydialkyl-diarylsiloxane. When the diaryl is included within this range, the refractive index may be improved and the low glass transition temperature of dialkyl can be maintained, which can result in improvement of low temperature impact strength.
- The polydialkyl-diarylsiloxane may include dialkyl and diaryl. Examples of the alkyl include without limitation C1 to C20 alkyl, for example, methyl, ethyl, propyl, butyl, t-butyl, and the like, and combinations thereof.

- The copolymer of polydialkyl-diarylsiloxane and polydialkylsiloxane may include about 50 to about 95 wt % of polydialkyl-diarylsiloxane and about 5 to about 50 wt % of polydialkylsiloxane. When a copolymer includes polydialkyl-diarylsiloxane and polydialkylsiloxane at the above ratio, deterioration of polymerization stability due to steric hindrance may be inhibited.
- The polysiloxane copolymer including an aryl group can have a viscosity of about 1 to about 1000 cSt at 25° C., and in another embodiment, a viscosity of about 4 to about 500 cSt at 25° C. When the polysiloxane copolymer has a viscosity within the above ranges, an excellent balance of properties such as impact resistance and transparency may be obtained.
